SPRING, Texas (FOX 26) - “We see a lot of negative things in law enforcement," says Harris County Precinct 4 Constable Mark Herman. "This is the reason we wear the badge. This is the reason that we get up every day and fight the good fight.”

Pleading for help from the public, Constable Herman released graphic video of what happened early on Friday morning. A woman is seen going up to her check cashing business with $75,000 dollars in her bag. Her husband was inside at the time. A man in a sport utility vehicle then drives up and begins to attack her, trying to take the money.

“There was a first vehicle that pulled up that had the suspect that got out the second vehicle was the Chrysler 300," describes Constable Herman. "That’s the individual that we got some pretty good quality video that we were hoping we would get him identified."

That second suspect began assaulting the husband and wife as well. The video then shows him run around his car, get in and then reverse the vehicle over the couple, before driving away. The woman is still able to hold onto the bag of money the entire time.

“Right after that, our deputy observed what’s going on from a distance," says Constable Herman. "He gets there. There’s some other citizens that did also come to the aid of the victim.”

David Dowell Mitchell, 31, was arrested and charged with aggravated robbery. Travonn Johnson, 27, was arrested on Monday. Investigators believe Johnson was driving the Chrysler 300.

The man and woman who were attacked were taken to an area hospital where she is listed in critical condition, but they are both expected to recover from their injuries.

Anyone with information about the brazen crime is encouraged to contact the Harris County Precinct 4 Constable's Office or Crime Stoppers of Houston by phone at 713-222-8477 (TIPS).
